A client cannot associate to an AP even though the correct SSID is selected. The technician confirms the passphrase is correct. What should be checked next?
Answer: Client's MAC address and whether MAC filtering is enabled
If credentials are correct but association fails, MAC address filtering on the AP may be blocking the client.
What is the primary role of a RADIUS server in an enterprise WLAN deployment?
Answer: Authenticate users and authorize network access via 802.1X
A RADIUS server provides centralized authentication, authorization, and accounting (AAA) for 802.1X-based enterprise WLAN security.
Which antenna type radiates power equally in all horizontal directions and is commonly used in indoor AP deployments?
Answer: Omnidirectional antenna
Omnidirectional antennas radiate RF energy in a 360-degree horizontal pattern and are the standard choice for general indoor coverage.
A site survey reveals that channel 6 is used by three neighboring APs in the same area. What is this condition called?
Answer: Co-channel interference
Co-channel interference occurs when multiple APs use the same channel in the same coverage area, causing contention and performance degradation.
In a centralized WLAN architecture, where is client data traffic processed before reaching the wired network?
Answer: At the Wireless LAN Controller (WLC)
In a centralized (controller-based) architecture, data traffic is tunneled to the WLC, which then forwards it to the wired network.
What is the maximum legal EIRP for a point-to-multipoint (PtMP) 5 GHz outdoor link under FCC rules?
Answer: 4 watts (36 dBm)
The FCC allows up to 4 watts (36 dBm) EIRP for point-to-multipoint 5 GHz outdoor deployments in the UNII-1 and UNII-3 bands.
A technician is deploying APs in a high-density auditorium. Which cell size strategy should be used?
Answer: Use small cells with lower transmit power to reduce co-channel interference
High-density environments benefit from smaller cells with lower transmit power, distributing clients across more APs and reducing interference.
